Although my knowledge is limited, I asked a question yesterday about smithing in the states of Runeterra. And thanks to Pizza Steve. I now know where they with be.
The Salamanders are the XVIII Legion of the Adepts Astartes of the 40 first millennium. Their Primarch, Vulkan, as an infant was raised by a Master Craftsmen teaching him all he knows. After a few years, Vulkan became a hulk of a man and was soon teaching master-smiths metalworking techniques lost during the Age of Strife.
Thanks to the Pizza, the Salamanders will be around in 3 states. Demacia, Freljord and Noxus. Creating the greatest weapons and armor forthe fines soldiers in the states. Of course, you may find a retired Salamander Ionia, which is pretty rare in many cases considering they don't travel date unless it's to find their materials to craft more weapons and armor
For their religious beliefs, they still hope for the Great Ornn to return one day, just like many others in Freljord.
I'll be making more post and polls soon. Please gimme your opinions on this, criticism is also accepted
